Longicornia Malayana. IGl 



formia ; tibits brevissimae ; tarsi vix dilatati. Pro- et meso- 



sterna depressa. 

 In some respects this genus may be considered as interme- 

 diate between Sthen'ias and Xylorhiza. All three genera are 

 distinguished by their strong antennary tubers, which, being 

 approximate or even contiguous at the base, create, as they di- 

 verge outwards and forwards, a deep hollow in that part of the 

 head between them. From each other they may be distinguished 

 at once by the form of the scape, slender and curved in Sthenias, 

 stout and elongato-cylindrical in /Etholopus, and thick at the apex, 

 gradually contracting towards the base, in Xylorhiza. There are 

 other points of difference, which will be seen on referring to their 

 characters. It may be mentioned that between Sthenias and 

 Xylorhiza, the Comte de Castelnau places nineteen genera. It 

 should be stated, however, that the latter is a most remarkably 

 distinctive genus in habit, although in its technical characters it 

 differs very slightly from Sthenias. The two species of ^tholopits, 

 described below, are very similar, although one is much darker 

 than the other, but the apices of their elytra will at one distin- 

 guish them. 



Mtholopus exutus. 



M. niger, subglaber ; elytris singulis plagis duabus griseo- 

 pubescentibus, apice truncatis. 



Hah. — Ceram. 



Black, nearly destitute of pubescence, except the patches on 

 the elytra ; head smooth and somewhat shining, punctures fine 

 and remote ; prothorax slightly constricted anteriorly, minutely 

 punctured ; scuteilum small, transverse •, elytra moderately punc- 

 tured, on each, dividing it into three nearly equal parts, are two 

 large dull-greyish pubescent patches, the apex truncate; body 

 beneath, legs, and antennae, dark brown, subnitid, the basal joiat 

 of the latter strongly punctured. 



Length 10 lines. 



JEtholopus scalaris. (PI. IX. fig. 6.) 

 JFj. cervino-pubescens, fuscescente varius ; elytris singulis 

 plagis duabus albescentibus, apicibus divaricatis, extus 

 oblique truncatis. 

 Hab. — Ceram. 



Closely covered with a fawn-coloured pubescence, shaded with 

 brownish ; head smooth and finely punctured below the eyes in 

 front, the remainder pubescent ; prothorax strongly constricted
